8、Flutter Paddiing组件

Padding组件处理容器与子元素之间的间距。

class MyApp extends StatelessWidget {
  const MyApp({super.key});
  @override
  Widget build(BuildContext context) {
    return Container(
      padding: const EdgeInsets.all(20),
     child: const Icon(Icons.abc_outlined),
    );
  }
}

class MyApp1 extends StatelessWidget {
  const MyApp1({super.key});

  @override
  Widget build(BuildContext context) {
    return const Padding(
      padding: EdgeInsets.all(20),
   child: Icon(Icons.abc_outlined),
    );
  }
}
